The Mid-Frequency Magnetic Property Modeling of an Electrical Steel Sheet Using a Dynamic JA model Considering Magnetic Domain Energy and Fractional Derivative Operator
2023 26th International Conference on Electrical Machines and Systems (ICEMS)(2023)
摘要
This paper proposes a dynamic Jiles-Atherton (JA) model considering magnetic domain energy and fractional derivative operator, and this model is verified to improve the modeling accuracy of magnetic property and calculate the magnetic field strength accurately under the frequency from 600Hz-1.8kHz. This approach was applied to estimate the magnetic property of a small scale, lkHz medium frequency transformer.
